I don't think any team will put them through much pressure. Perhaps Borussia Dortmund or Bayer Leverkusen could give them a bit of a challenge, but it wouldn't be surprising if we saw Bayern Munich lead the way until the end of the season. No team can dominate them in the league. The same can be said for Paris Saint-Germain in the French League. The German League, as a league won by Bayern Munich, will always be in history.
Bayern Munich could have as well experience the friendly with Chelsea also so that the play could have been use on what Chelsea score and the day Bayern Leverkusen went to them on away match, I no that Bayern Munich might not have been scored this 3 at nothing and even with the past PSG match Chelsea might not have even score 3 but because of the reluctant feeling of failure that constituted more goals. So actually Bayern Leverkusen or Borussia Dortmund will not push Bayern Munich beyond limits because so long as they have an above points or the same with either of them they will win as they always do before.
